splice_command_type

SCTE 35 Part 1

Enumerated values

Value	Dec	Name	Description	History
0x00	0	splice_null	A heartbeat or descriptor-only message. It carries no splice timing itself and is often used to keep a link alive or to deliver a segmentation descriptor on its own.
0x04	4	splice_schedule	Announces one or more future splice events well ahead of time. Each scheduled event is later confirmed by a matching splice_insert closer to air.
0x05	5	splice_insert	The classic splice_insert message: signals a specific splice in or out of the network feed at a given time, optionally with a break duration.
0x06	6	time_signal	Marks a point in time without directly commanding a splice. It carries meaning through the segmentation (or, in SCTE 35 Part 2, event) descriptors attached to it. It is widely used for modern segmentation and event signaling, though splice_insert remains in common use; the choice depends on the downstream contract and carriage (for example HLS EXT-X-DATERANGE maps both).	added 2011
0x07	7	bandwidth_reservation	Reserves a consistent amount of transport-stream bandwidth in a multiplex by keeping its PID's packets present at the intended repetition rate, rather than holding room for one specific later message. It signals no splice.	added 2011 (Reserved in the 2001 edition; defined from 2011.)
0xff	255	private_command	A vendor-specific command identified by a registered format identifier. Its body is defined by the owner, not by SCTE 35.	added 2011 (Reserved in the 2001 edition; defined from 2011.)
